【High Accuracy】The pH range is 1.00-14:00, while the CE and TDS digital meters have a digital range of 0-19990ppm. And this liquid crystal conductivity meter has an accuracy of 0.1. Immerse the item in the liquid for about 4 seconds, then you will know the quality of the liquid digitally. 【Automatic Calibration】The pH tester can perform three-point automatic calibration (accuracy is 0 .1ph). No adjustment is necessary before use. It is very convenient to use. 【Color Display】Different from other TDS meters, this TDS meter adopts backlight, which makes data display clearer. Data can be easily viewed even in dark environments, and the pH meter also has a color display. Although it has a specific digital display, it can also indicate the pH of the water through four colors: red, orange, green and blue. 【Multi-purpose】The pH- meter can be widely used in: testing drinking water, aquarium, swimming pool, spa and wine, tap water, well water, sea water, amniotic fluid, breakthrough ,
